Abstract
A portable rock crusher (10)is adapted for attachment to a boom (16) of an earthmoving vehicle (14). The crusher has a hopper (32) with a material inlet (49) and a material outlet (44) spaced from the inlet. A pair of jaws (46,48) is located within the hopper and positioned between the inlet and outlet. The jaws are movable relative to one another to vary the spacing therebetween and an actuator (68) is provided to control relative movement between the jaws. Material moving from the inlet to the outlet thereby passes between the jaws and is crushed upon relative movement of the jaws to provide an aggregate at the outlet.
